Description

Technical Field

[0001] This utility model relates to the field of inverters, and in particular to an off-grid bidirectional rectifier inverter. Background Technology

[0002] An inverter is a converter that transforms DC power into AC power with fixed frequency and voltage or frequency and voltage regulation. It consists of an inverter bridge, control logic, and filter circuits, including a bidirectional rectifier power inverter. Since the bidirectional rectifier power inverter generates a lot of heat when doing work inside, it usually uses heat sinks on the outside for auxiliary heat dissipation.

[0003] The prior art patent application with publication number CN221807554U, through the arrangement of a fixed plate, heat sink, and movable ventilation pipe, facilitates the disassembly and installation of the fixed plate, heat sink, and ventilation pipe. Furthermore, the arrangement of the heat sink extending into the inverter housing increases the heat conduction area of ​​the heat sink, improves the speed of heat absorption, and accelerates the efficiency of heat exchange between the heat sink and the outside environment. The airflow inside the ventilation pipe further accelerates the efficiency of heat exchange between the ventilation pipe and the inside of the inverter housing. The twisting deflection ring drives the rotating ring to connect with the inner wall of the recessed groove, facilitating the limiting and fixing of the ventilation pipe. Simultaneously, the ventilation pipe limits and fixes multiple heat sinks, facilitating the installation of the fixed plate and heat sinks.

[0004] However, current inverters and their housings are fitted with multiple heat sinks for easy heat dissipation, and are installed and fixed together by long ventilation ducts. When multiple heat sinks are installed in this way, if the heat sinks that have been used for a long time need to be cleaned or removed, the entire ventilation duct needs to be removed for operation, and it is not possible to disassemble and replace them individually.

[0005] Therefore, it is necessary to provide an off-grid bidirectional rectifier inverter to solve the above-mentioned technical problems. Utility Model Content
